Experiment 1


Stories in Stone Salt Crystals


Materials: 2 cups (one full of salt, the other of water), spoon, tape, plastic plate, stick
1. Add water to the salt and stir with the stick
2. Tape the spoon to the plate.
3. Pour a little of the solution into the spoon from the cup.
4. Let out to evaporate.
5. When evaporated, examine. Notice the structure of the crystal. If it is square then the solutin was undisturbed.

Experiment 3



Stories in Stone How do Igneous Rocks Form



Crystal Formation at Room Temperature

Procedure
1.Place a very small amount (less than 1/8 teaspoon ) of salol on a metal spoon.

2.Melt the salol by holding the spoon more than an inch (3cm)above the flame.

3.Remove the spoon from the flame.

4.Add a few grains of salol as "seed crystals."

5,Prop up the handle so the spoon stays level.

6.Look at the crystals with a magnifying lens,and draw what you see.


Crystal Formation at Low Temperature

Procedure
7. Remelt the crystals in one of the spoons.

8. Rest the bowl of the spoon on an ice cube.

9. Draw the shape of the crystals when the salol cooled
at a low temperature. Use the magnifier to closely examine the crystals.
